Anti-periodic solutions for semilinear evolution equations
Journal of Mathematical Analysis and Applications, 2002 The authors study the existence problem of anti-periodic solutions for the following first-order nonlinear evolution equation \[ \begin{cases} u'(t)+Au(t)+F(t,u(t))=0, &t\in\mathbb R\\ u(t+T)=-u(t), &t\in\mathbb R,\end{cases} \] in a Hilbert space \(H\), where \(A\) is a selfadjoint operator and \(F\) is a continuous nonlinear operator.

International Journal of Applied Mathematics and Computer Science, 2020 A class of Clifford-valued high-order Hopfield neural networks (HHNNs) with state-dependent and leakage delays is considered. First, by using a continuation theorem of coincidence degree theory and the Wirtinger inequality, we obtain the existence of ...

Analytic continuations of de Sitter thick domain wall solutions [PDF]
, 2002 We perform some analytic continuations of the de Sitter thick domain wall solutions obtained in our previous paper hep-th/0201130 in the system of gravity and a scalar field with an axion-like potential.

Affine-periodic solutions by asymptotic and homotopy equivalence
Boundary Value Problems, 2020 This paper studies the existence of affine-periodic solutions which have the form of x ( t + T ) = Q x ( t ) $x(t+T)=Qx(t)$ with some nonsingular matrix Q.

Anti-periodic solutions for nonlinear evolution inclusions
Journal of Evolution Equations, 2018 The authors consider the nonlinear anti-periodic evolution inclusion \[ \begin{aligned} & -u'(t)\in A(t,u(t))+F(t,u(t))\text{ a.e. on }I=[0,T],\\ & u(0)=-u(T),\end{aligned}\eqno{(1)} \] where \(\left( X,H,X^{\ast }\right) \) is an evolution triple, \(A:I\times X\rightarrow 2^{X^{\ast }}\) and \(F:I\times X\rightarrow 2^{H}\). \ It is not assumed that \(

Anti-periodic solution for fuzzy differential equations
上海师范大学学报. 自然科学版, 2021 In this paper, using differential inclusions’ approach, we obtain existence results of antiperiodic solutions for a class of fuzzy differential equations. An example shows the feasibility of the main results.

Anti-periodic solutions for second order differential equations
Applied Mathematics Letters, 2011 The authors consider the existence of anti-periodic solutions for the following second order differential equation \[ (p(t)x')'+f(t,x)=0,\tag{1} \] where \(p\in C^1(\mathbb R)\) is a given \(T\)-periodic function, and \(p(t)>0\); \(f\in C^1(\mathbb R\times\mathbb R)\) is a \(T\)-anti-periodic function.
